User manual DBX 266XL COMPRESSOR / GATE

[. . . ] When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. As colours of the cores in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: · The core which is coloured green and yellow must be connected to the terminal in the plug marked with the letter E, or with the earth symbol, or coloured green, or green and yellow. ⷠThe core which is coloured blue must be connected to the terminal marked N or coloured black. ⷠThe core which is coloured brown must be connected to the terminal marked L or coloured red. [. . . ] When the Compressor and Expander/Gate are both active, the meter displays the maximum amount of gain reduction for whichever function is greater - Compressor or Expander/Gate. oUTPUT GAIN (dB) Control This control sets the overall gain of the 266XL , from -20dB to +20dB. The OUTPUT GAIN control is especially useful to compensate for the RMS level decrease which results from the 266XL's dynamic processing effects. after you adjust the 266XL's controls for the desired amount of compression , set the OUTPUT GAIN to add the same amount of gain that is shown on the GAIN REDUCTION meters. For example, if the average amount of gain reduction shown on the meters is 10dB, then setting the OUTPUT GAIN control to +10dB will compensate for the 10dB average level reduction at the output. Note: the 266XL's Compressor and Expander/Gate control settings are interactive and can affect gain, so watch your playback levels. Note: Setting the Compressor RATIO to 1:1 will turn the Compressor off, regardless of the setting of the Compressor THRESHOLD control and BELOW/OVEREASY/ABOVE LED status. Setting the Compressor THRESHOLD control to +20dB will prevent all but the highest level peaks from being compressed. The amber THRESHOLD LED turns on when the signal is in the OverEasy region. When the switch is out, the 266XL operates as a hard-knee compressor, and the amber LED does not light. Compressor THRESHOLD Control and LEDs (BELOW/OVEREASY/ABOVE) Adjust this control to set the threshold of compression from - 40dB to +20dB. In hardknee mode, the threshold of compression is defined as the point above which the output level no longer changes on a 1:1 basis with changes in the input level. In OverEasy mode the threshold of compression is defined as the middle of the OverEasy threshold region, that is, "half-way" into compression. The three THRESHOLD LEDs indicate the relationship of the input signal level to the threshold of compression. The green LED lights when the signal is BELOW threshold, the red LED lights when the signal is above threshold, and the yellow LED lights when the OVEREASY switch is depressed and the input signal is in the OVEREASY range. The 266XL's OverEasy compression permits extremely smooth, natural sounding compression, without artifacts, due to the gradual change of compression around the threshold. With OverEasy compression, input signals begin to gradually activate the 266XL's internal gain change circuitry as they approach the THRESHOLD reference level. They do not get fully processed by the RATIO, ATTACK and RELEASE controls until they have passed somewhat above the THRESHOLD reference level. As the signal level passes the THRESHOLD level, processing increases until it is fully processed to the extent determined by the control settings. In hard-knee mode, the 266XL can provide abrupt compression effects as well as hardlimiting applications. Note that when in hard knee mode the amber LED will not light as the input signal passes across the threshold. The signal is either being compressed (over threshold) or it is not being compressed (under threshold). [. . . ] Each 266XL is tested, burned-in and calibrated at the factory and should require no internal adjustment of any type throughout the life of the unit. We recommend that your 266XL be returned to the factory only after referring to the manual and consulting with dbx Customer Service. Our phone number, Fax number and address are listed on the back cover of this manual. When you contact dbx Customer Service, be prepared to accurately describe the problem. [. . . ]
